An Iv Collision Avoidance Algorithm - Strengthening The Wep

The Wired Equivalent Privacy (WEP) protocol,for networks based on 802.11 standards has been shown to have several security flaws. One of the most important of them is the Initialization Vector (IV) collision problem which is a threat to the message privacy. We develop an IV avoidance algorithm that eliminates IV collision problem. Tire idea is to partition the IV bits among different wireless hosts in a predetermined manner unique to every node. We can use all possible 2(24) different IVs without making them predictable for an attacker. Our proposed algorithm eliminates the IV collision ensuring Message Privacy that further strengthens security, of the existing WEP.
